Many things are hard to believe!
We don’t place ice cream on a pedestal with any degree of fever. Belief does not come into it. It’s just another small pleasure, slightly less satisfying than a 700ml Islay single malt. One tends to last longer than the other around here. However over indulgence of either may not be good for your health.
There is food science as to why soft serve ice cream is preferred by some. How it is produced makes it appear whiter (marketing purity), uses less milk fat (Lower cost of ingredients), and due to the added air (free ingredients) has a smoother and creamier texture.
One view is soft serve is just like regular ice cream that has been watered down and fluffed up. Almost good enough for a shonky? Or it should be one third the price? My gran would have agreed - “you are not wasting your money on that rubbish now are you?” It helped to just smile and nod knowing a Choc Top at the movies was the only way to go!
